    Title: HIGH TORQUE ROTARY MOTOR
    FIELD OF THE INVENTION
    [0001] The invention relates to a rotary power motor, particularly to a rotary powermotor equipped with a multi lobe motor ring and the manufacturing method thereof.
    BACKGROUND OF THE INVENTION
    [0002] A conventional hydraulic rotary motor is typically manufactured in a way thatvanes project from a rotor and rotate about a central axis of rotation. The motor includeshousing where the vanes and the housing define a plurality of chambers. The motortypically has a single inlet for a working medium to enter the plurality of chambers and asingle outlet for the working medium to exit the plurality of chambers where the torque torotate the rotor is limited by the single pair of inlet and outlet.
    [0003] The rotor in the conventional hydraulic rotary motor is designed to move indirections perpendicular to the central axis of rotation. A volume of each of the chambers inrelation to an angular position of the chamber varies as the rotor moves in directionsperpendicular to the central rotation axis during rotation of the rotor. In particular, thevolume of a chamber is at its minimum and the pressure of the working medium in thechamber is at maximum as the chamber rotates past the inlet. The volume of the chamberincreases and the pressure in the chamber decreases as the chamber approaches theoutlet. Such a movable rotor induces uneven pressure loading and thus a severe side loadto a shaft supporting the rotor. Additionally, the torque acting on each vane is not consistentduring rotation of the rotor. Accordingly, it would be desirable to have a motor thataddresses some of the issues described above.

An outercircumferential surface 33 of the multi lobe motor ring 30 may include one or more of pairs ofinlet flow groove 31 and outlet flow groove 32. The inlet flow groove 31 may be aligned withthe inlet port 11 of the outer port ring 10 (see FIG. 2) so that the inlet flow groove 31 canreceive the working medium from the inlet port 11. Similarly, the outlet flow groove 32 maybe aligned with the outlet port 12 of the outer port ring 10 (see FIG. 2) so that the mediumflowing in the outlet flow groove 32 may be discharged by way of the outlet port 12.
    [0028] The multi lobe motor ring 30 may include a plurality of lobes 36. In oneaspect, a number of the lobes 36 may be 2 or more, preferably, 6 or more. Optionally, anumber of the lobes 36 may be 8 or more. Each of the plurality of lobes 36 may include apair of inlet 34 and outlet 35.

In one aspect, theinlets 34 at the plurality of lobes 36 may be aligned with the inlet flow groove 31 so that eachof the inlets 34 can receive the working medium from the inlet flow groove 31 and introducethe working medium to the corresponding concave working chamber 38. Similarly, theoutlets 35 at the plurality of lobes 36 may be aligned with the outlet flow groove 32 so thatthe outlet flow groove 32 can receive the working medium exiting the concave workingchambers 38 by way of the outlets 35. Due to the continuous medium flow loop among theouter port ring 10, the multi lobe motor ring 30, and the chambers 38, the rotary mediumpower motor 100 may produce higher torque compared to a conventional hydraulic motor.
    [0030] FIG. 4 depicts a perspective view of a vane 40. The vane 40 may include oneor more subvanes 41, 42. In one aspect, the vane 40 may be split into a pair of subvanes,first 41 and second 42 subvanes where the pair of first 41 and second 42 subvanes canslide with respect to each other while remaining, in part, in contact with each other.

The round shapes 441, 442 of the vane40 may be in contact with the inner circumferential surface of the multi lobe motor ring 30(see FIG. 1), thereby forming a seal between the vane 40 and the inner circumferentialsurface of the multi lobe motor ring 30 during rotation of the inner rotor 50 (see FIG. 1). Theround shapes 441, 442 of the vane 40 may reduce a frictional force between the vane 40and the inner circumferential surface of the multi lobe motor ring 30 while enabling the vane 40 to maintain a contact with the inner circumferential surface of the multi lobe motor ring 30during rotation of the inner rotor 50. In some aspect, a number of vanes 40 may be largerthan a number of lobes 36 to prevent bypass flow of the working medium.
    [0031] FIG. 5 depicts a top view of a vane 40 having a coil spring and FIG. 6 depictsthe corresponding perspective view. Each of the first 41 and second 42 subvanes mayinclude an offset slot 411, 422 in the interior of the subvane where an elastic member 430can be placed in the offset slots 411, 422. The elastic member 430 may include a spring. Insome aspects, the elastic member 430 may include a coil spring, a flat spring or the like.While the first 41 and second 42 subvanes may remain, in part, in contact with each other,one end 431 of the coil spring 430 may be in contact with a surface of the offset slot 411 inthe first subvane 41, thereby pushing the end 451 of the first subvane 41 forward.Resultantly, the end 451 of the first subvane 41 may form a contact with an inner surface ofthe first end plate 21 (see FIG. 1), thereby forming a seal between the vane 40 and the firstend plate 21. Similarly, the other end 432 of the coil spring 430 may be in contact with asurface of the offset slot 422 in the second subvane 42, thereby pushing the end 452 of thesecond subvane 42 to the opposite direction to the forwarded first subvane 41. Resultantly,the end 452 of the second subvane 42 may form a contact with an inner surface of thesecond end plate 22 (see FIG. 1), thereby forming a seal between the vane 40 and thesecond end plate 22. This type of split vane design may allow the vanes to force a seal tothe end plates 21, 22 so that the motor 100 can work at much higher medium pressurescompared to a conventional vane motor.
    [0032] FIG. 7 depicts a top view of a vane 40 having a flat spring and FIG. 8 depictsthe corresponding perspective view where the flat spring 460 is placed in the offset slots411, 422. Similar to the coil spring 430 in FIGS. 5-6, while the first 41 and second 42subvanes may remain, in part, in contact with each other, the end 451 of the first subvane 41 is pushed forward, thereby forming a seal between the first subvane 41 and the first endplate 21. The end 452 of the second subvane 42 forms a seal between the second subvane 42 and the second end plate 22.
    [0033] FIG. 9 depicts a perspective view of the multi lobe motor ring 30, the pluralityof vanes 40 and the inner rotor 50.

The plurality of the vane slots 53 may becircumferentially arranged at equal angular intervals in the outer surface of the inner rotor50. Each vane 40 may be positioned within the corresponding vane slot 53 in a directionperpendicular to a central rotation axis a0 of the inner rotor 50. During rotation of the innerrotor 50 about the central axis a0 of the inner rotor 50, fluid pressure may cause the vane 40to slide outwardly so that the rounded sides 441, 442 of the vane 40 can be forced outsidethe vane slot 53 and form a contact with the inner circumferential surface of the multi lobemotor ring 30. In one aspect, the vane slot 53 may not require an expansion member topush the vane 40 outwardly to have the vane 40 in contact with the inner circumferentialsurface of the multi lobe motor ring 30. Alternatively, the vane slot 53 may include anexpansion member to augment the outwardly-acting centrifugal force. The expansionmember may include a spring, a compressed gas or any other suitable means to augmentthe outwardly-acting centrifugal force.
    [0034] The inner rotor 50 may include one or more sealing ridges 51. The sealingridge 51 may be placed between a side of the inner rotor 50 and the end plates 21, 22 (seeFIG. 1). The sealing ridge 51 may form a seal between the inner rotor 50 and the end plates21, 22 and reduce the pressurized area against the end plates. The inner rotor 50 mayfurther include a drive slot 52. The drive slot 52 may hold the drive 60 (see FIG. 2) passingthrough the inner rotor 50. Optionally, the drive 60 may be connected to the drive slot 52. Inone aspect, the central rotation axis a0 of the inner rotor 50 may be aligned with the passingdirection of the drive 60. In some aspects, the inner rotor 50 may not move in a directionperpendicular to the central rotation axis during rotation of the inner rotor 50.
    [0035] FIG. 10 depicts an end view of the multi lobe motor ring 30, the plurality ofvanes 40, and the inner rotor 50. The multi lobe motor ring 30 may enclose the plurality ofvanes 40 and the inner rotor 50. The inner circumferential surface of the multi lobe motorring 30 may include the plurality of lobes 36. The inner circumferential surface of the multilobe motor ring 30, the outer circumferential surface of inner rotor 50 and the end plates 21,22 (see FIG. 1) may form a plurality of working chambers 38. In one aspect, each chamber38 may be formed by two adjacent lobes 36, the inner circumferential surface of the multilobe motor ring 30 and the outer circumferential surface of inner rotor 50 where the chamberis closed by two end plates 21, 22. [0036] Each chamber 38 may have an equal volumewith respect to each other. In some aspects, the rotation axis a0 of the inner rotor 50 may befixed so that each chamber 38 may maintain the equal volume during rotation of the innerrotor 50. The working medium entering the inlet port 11 of the outer port ring 10 (see FIG. 1)may be received by the inlet flow groove 31 (see FIG. 1) on the outer circumferential surface of the multi lobe motor ring 30. The working medium on the inlet flow groove 31 may entereach chamber 38 by way of the inlet 34 in each lobe 36 and act on a vane 40 projectingfrom the inner rotor 50 to generate a torque, thereby rotating the inner rotor 50 in aclockwise or counter clockwise direction about the central rotation axis a0 of inner rotor 50.Similarly, the working medium may exit the chamber 38 by way of the outlet 35 and may besubsequently discharged by way of the outlet groove 32 and the outlet port 12 of the outerport ring 10 (see FIG. 1). The medium flow path according to the disclosure may allow theworking medium to feed all of the inlets and outlets in the plurality of lobes 36 withoutrequiring multiple external connections. In addition, this type of medium flow path may allowthe rotation of the rotor 50 reversible without removing and repositioning the motor 100.
    [0037] FIG. 11 depicts a portion of an exemplary chamber 38. The working mediumentering the working chamber 38a by way of inlet 34a may act on the vane 40 projectingfrom the inner rotor 50, thereby rotating the inner rotor 50 as indicated by the arrow. Afterrotating the inner rotor 50, the working medium may exit the chamber 38a by way of outlet35a. In one aspect, a working chamber may include an inlet and an outlet. In someaspects, a working chamber may receive a working medium by way of an inlet anddischarge the working medium by way of an outlet that may be located in the nearestneighboring lobe in the rotation direction of the inner rotor 50. In various aspects, a workingchamber may receive a working medium by way of an inlet and discharge the workingmedium by way of an outlet that may be located in the nearest neighboring lobe in theclockwise rotation direction of the inner rotor 50.
    [0038] Each chamber may produce an equal amount of torque acting on the vanes40. The plurality of lobes including inlets 34 and outlets 35 may generate a torque arm ateach of the plurality of the vanes 40. In one aspect, the torque rotating the motor 100 maybe multiplied by the number of lobes 36. In various aspects, the rotary power motor 100may need no side load and no secondary nut runner. In some aspects, all the input energymay be turned into continuous rotation and thus may achieve a faster and strongerrotational force compared to a conventional hydraulic motor.
